FASTENING DEVICE FOR' WALL-BOARD, &c.

Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed. May 2S, 1919. Serial No. 300,384.

To all whom t may concern Be it known that I, ,CHARLES A. UPSON, a citizen of the United States, residing in Lockport, in the State of New Y'ork, have invented certain new and useful Improvements in Fastening Devices for Wall-Board, &c., of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This invention relates tofastening. devices for wallboard, etc., of the same general character as that shown and described in Letters Patent of the United States granted to Julius E. B. l/Vitli, No. 1,297,523, dated Mar. 18, 1919, and in Letters Patent of the United States granted to the present applicant, No. 1,297,611, dated Mar. 18, 1919, and it has for its object to cover a specific forni of such fastening device which may be of advantage under some conditions of use or with some kinds of material. In the forms of fastening devices shown in said several Letters Patent the prongs which are struck up from the plate are shown as inclined outwardly or away from each other, although they are described and covered only as spreading laterally without regard to their inclination toward or from each other. In the specific form of the fastener which is the subject of the present invention such struckup prongs, or some of them, are inclined or bent toward each other so that, when they enter the material, they may have something of a clenching action. Another feature of the improvement has for its special object facility in manufacture and in use. The invention will be more fully explained hereinafter with reference to the accompanying drawing in which it is illustrated, and in which* Figure 1 is a view of the improved fastener in elevation, before the edge and face prongs are bent. l

Fig. 2 is a view of the same as seen from the left hand in Fig. 1, but with the edge prong bent into position for application to the studding and the face prongs bent to engage the wallboard.

Fig. 3 is a view of the same as seen from above in Fig. 2, the position of the Wallboard, as it is being applied, being also Shown.

Fig. 4 is a side view similar to Fig. 3, but showing the wallb'oard driven home from the fastener.

The improved fastener consists of a thin. flat, metal plate a of any desired form, it being shown in the drawing as generally rectangular. It has, extending from one edge outward, a wide prong b, which ifiay vbe stiffened by corrugation as at b, which may be driven into the studding to which the wallboard is to be secured. In its other side, extending outward from the edge, is a corresponding notch 02,*wliich may be utilized as a ,nailing slot, if so desired. The formation of the plate in this manner, with a prong on one side and a corresponding notch in the other side, permits the fastener to be stamped out from a strip or sheet of metal without waste. The plate has also, preferably struck up because of economy in manufacture, two prongs c which are slightly bent toward each other or toward the central plane, and two prongs c which are slightly bent away from each other or away from the central plane so that when the wallboard is forced against them, as by pounding, they will enter the wallboard and will be spread laterally, the prongs c toward each other and the prongs c away from each other. clenching action as between themselves and also as between each prong 0 and the corresponding prong c on the same side. A single perpendicular prong d may be provided for the purpose of preventing slip of the wallboard to one side or the other when it is beingapplied.

In the use of the improved fastener the pron 0l (which may be left flat if so desired may first be driven into the studding to hold the fastener in place, and a nail e may then be driven into the notch In to securely hold the fastener to the-studding. When it has been secured'in position the wallboard is placed against the ends of the prongs c and c and is forced home, as by blows of a hammer or mallet, against a piece of board laid against the front surface of the wallboard or otherwise by pressure. In this operation prongs c are bent inwardly farther toward each other and the prongs c are bent outwardly farther away from each The prongs c may thus have a other, the perpendicular prong l being made at the same time to enter the Wallboard so as to prevent lateral slip. At the inner end of the nailing slot or notch b2 the plate is slightly counter-sunk, as shown, to receive the head of the nail.

I claim as my invention:

l. A blind fastener for wallboard, etc., to be placed between the Wallboard and stud-- ding to which the Wallboard is to be fastened, consisting of a thin, Hat, metal plate, adapted to be secured to the studding and having struck-up prongs with pointed ends and so bent toward each other that they Will enter the Wallboard and be bent farther to engage and cleneh it, and other prongs having pointed ends and so bent away from each other that they Will enter the Wallboard and be bent farther to engage and retain it,

izaase When the Wallboard is forced against the 20 fastener.

2. A blind fastener for Wallboard, etc., to be placed between the Wallboard and the studding to which the ivallboard is to be fastened7 consisting of a thin, flat, metal plate, having in one side a notch to receive a fastening means to secure the plate to the studding and on the opposite edge a correspondingly shaped prong bent to engage the studding and provided on the side toward the Wallboard with struck-up prongs having pointed ends and so bent that they will enter the Wallboard and spread latei-, ally to engage and retain it when the Wallboard is forced against the fastener.

This specication signed this 23rd day of May, A. D., 1919.
